IMPROVEMENT IN STEAM BELL-RINGER-S.

Specification forming part of Letters Patent No. 134,719, dated January7, 1873.

To all whom it may concern: y

Beit known that we, JOEL WEST and OR- REN M. PARKER, of Quincy, countyoi' Adams and State o Illinois, have invented certain Improvements inSteam Bell-Rin gers, of which the followingis a specification. Y

The nature of our. invention relates to improvements on the steambell-'rin ger for which we obtained Letters Patent the 25th day of June,1872; and the invention consists, first, in extending the valve-stemthrough the end of the steam-chest most distant from the bell, v

or, in other words, through both ends of the steam-chest, so thattappets may be placed on the extended ends of the piston-rod, describedin our said patent, which, striking the extended ends of the valve-stem,may communicate thereto a reciprocating motion from the movement of thepiston-rod, second, it consists in the construction and arrangement of atubular valve with an exhaust-opening at the end of the steamchest, thesteam from one of the piston-cylinders passing out direct, and from theother passing out' longitudinally through the tubular valve to theexhaust-opening; third, it consists in the arrangement and constructionof all the parts to form a compact, simple machine, which can be easilyand readily attached at the desired place on an engine, all ashereinafter fully described.

In the accompanying drawing, Figure lis a top view of a machineembodyingourinvention; Fig. 2 is a sectional view on a plane centrallythrough the cylinder and valve-chest, longitudinally; Fig. 3 is atransverse sectional view of Fig. l on the line a: x, showingthe end toand Fig. 4 is a view of the tubular valve a side elevation.

A B represent, respectively, the cylinder and steam-chest, formed, asshown, of one piece of metal, with a ange, A', projecting annularly fromone end, and pierced with holes c c c c, through which bolts may beinserted to secure it in any desired place on the engine. Cissteam-inlet pipe. D is exhaust-opening. E is valve in steam-chestB,constructed as hereinafter described. G and G' are steam-passages fromsteam-chest B to cylinder A. H -H' are relief-passages. I is thepiston-head, with annular steam -packing rings z' t', and made lengthyfor operation with the steam-passages G G' and relief -passages H H',substantially the same as in our aforesaid patent. J is piston-rodworking in suitable packing-boxes in each end of the cylinder A,extending beyond the cylinder-heads at J and J", and provided with ahandle, K, at the end J ',and connectedwith the bell at the other, thesame as in our patentof June 25, aforesaid. L L are tappets or arms, oneon each end J J of the piston-rod. M M' are valve-rods, one on each endof the valve E, Working in suitable packing-boxes in each end of thesteam-chest B, and extending beyond the steam-chest heads, as shown inthe drawing. N is a cock in the pipe O. The valve E is tubular, with itscentral portion contracted, and its ends made to t accurately thecylindrical bore of the steamchest B, and is of such length that whenstanding centrally longitudinally in the steam-chest its two ends willcover the steam-passages G G', except a small portion of each. The rodsM M' are connected to the valves E by bails e e.

For cheapness of construction and neatness and compactness of form,andconvenience of attachment in Working position, the steam-cylinder A andsteam-chest B are cast in one piece, with an annular flange, A', at oneend. The device may be set up in any desired position, but preferably asshown at Fig. 3, with the piston-rod J horizontal, and with the lowerside of the steam-chest B, or the exhaustopening from the steam-chest,at its lowest side. It may be attached to the side of the cab of alocomotive, or other vertical base, by cutting a hole therein to passthe body through to the iiange A', where it may be secured by boltsthrough the holes c c c c.

The operation is as follows: The connection with a steam-reservoir is bythe pipe C. The flow of steam through the pipe C may be regulated by thecock N. The operation of the piston I in relation to the ports G G', andexhaust-openings H H', and to the bell, vare the same as in our saidpatent of June 25, 1872, the piston being carried throughout the centralportion of its stroke by the force of the steam, andthrough thebeginning and end of its strokes at each end of the cylinder,alternately, by the gravity and momentum of the bell. To start thebellthe handleKmaybe taken hold of, and the piston I moved thereby tothe position shown by dotted lines at Fig. 2, the tappet L striking thevalve-stem M and bringing it to the left, and opening thereby thesteamway G', and allowing steam from the annular spacesurrounding thecentral part of the valve E to enter andl ll thejway G', at the sametime drawing the bell from its vertical position toward the cylinder A.Now, by releasing the hold of the handle K, the bell will, in swingingbackto a vertical position, carry the piston I to the position shown byfull lines in Fig. 2, and steam entering through the now open Way G',will carry the piston I to the right until the tappet L' strikes thevalvestem M', and carries the valve E to the right to the position shownat Fig. 2, cutting off the further admission-of steam through the WayG', the momentum which the bell has acquired completing the stroke ofthepiston to-the right, and carrying the valve E to the right, openingthereby port G' for the exhaust of steam in that end of the cylinder andsteamchest, through the opening D, and at the same time open the port Gfor the admission of steam When the gravity of the bell carries thepiston I back, as described in our former patent, until the tappet Lstrikes the Valve-stem M, and the steam carries the piston toward theleft-hand end of its stroke, and With it the valve E, to the positionshown by dotted lines at-Fig. 2, opening vagain the port G' for theadmission o f steam, and the port G to exhaust centrally through thevalve E, as shown by arrows, to the 'opening D, and thus continuouslyuntil stopped by taking hold of the handle K and bringing',v all ofV theparts into the relative position shown at Fig.`1.

When the engine is put up 1n the position described, it will be evidentthat the condensed steam in the steam-chest B lnay run out at theexhaust D.

The length of the valve E is such as to al- Ways allow a Very smallamount of opening to both ports G G' for drainage, when standing as atFig. 2.
